Computer Assignment I: Look Angle Determination
Due: Saturday, Oct. 6 , 2012
You are required to build a Matlab function for geostationary satellite look-angle determination. The Matlab function should accept four inputs; namely: the longitude and the latitude of the earth station and the sub-satellite point. The function should produce three different outputs; namely: the elevation, the azimuth angle, and the distance to the satellite, d. Your program should work for any combination of inputs
Function [El,Az,d]=lookangle(Ls,ls,Le,le)
Test your program by finding the look angles and d for Badr 4 and ArabSat-5A. Assume the earth station is located in Dhahran (B59). Compare your result with the one obtained using the User Tools from ArabSat Website. What is the percentage of error.
Find the look Angles, and the range to the satellite for Nilesat 101.
Mr. Fahad Al-Otaibi -in Dhahran, Saudi Arabia-claims that it is possible to receive signals from Brasilsat B1. Use your program to explore his claim and comment.
Under what condition, the above program can be used to find the Qibla (Direction to Makkah). Make another code for finding Qibla and compare with other resources in the internet
You need to submit a total of no more than four pages including the code. A hard copy should be submitted in the class on the due date and a soft copy ( report+m-file) should be submitted electronically.
Instructions:
Writing style and organization are very important (Quality not Quantity!)
Your names and serial numbers should be clearly presented on the first page as well as on the code.
A group of two students work together and submit one report. You will have to change your partner every computer assignment.
Remember to use (help, lookfor) commands.
This assignment accounts for good percentage of your total grade.
Allow yourself enough time. Do not work close to the due date.
Assignments are to be submitted during class time. Any late submission will result in low grade.
You can use the discussion group in the Course WebCT to discuss general ideas and questions.
Copying is the easiest way to loose points.
Good luck, Dr. Ali Muqaibel
